Detailed Description

Struct for previous, current, and next point for a curve.

In general, a segment Bi is defined by the control points Pi0, Pi1, Pi2, and Pi3, such that the the segment Bi passes through Pi0 and Pi3, and has a tangent of Pi1-Pi0 at Pi0, and Pi2-Pi3 at Pi3.

For the ith control point, the incoming tangent is defined by the vector from (xp,yp) to (x,y), that is: (xp,yp) = P(i-1)2 (x,y) = P(i-1)3 = Pi0

Similarly, the outgoing tangent is defined by the vector from (xn,pn) to (x,y), that is:

(xn,yn) = Pi1
